Are these valid cars?

Here is a pic of one of the invalid cars I mentioned in my cow in the canal blog. No the pic has not been distorted. They are allowed to go anywhere that bikes go and, according to Tim, the occupants take advantage of this and make cyclists' lives hell. It was pretty bad sharing a bike lane with them yesterday as they can travel as fast as a motorbike, but take up three times the room. But it is a great way for people with disabilities and the elderly to remain independent - my mother would have loved one!
